Battery Saver

When the battery saver is OFF, the RF source power is left ON at the end of the
sweep which consumes more battery power. This feature is used in CAT, NA,
and VVM modes when the internal source is turned ON.
Battery Saver is the ONLY FieldFox setting that must be made as a Preference
from the Quick Settings table. This setting remains until you change it again.
The FieldFox internal temps will run 2°C – 5°C cooler with the Battery
Saver on (the temperature range is dependent on the ambient temp).

—ON – To conserve battery power, the RF source power is turned OFF at
the end of each CAT, NA, and VVM mode sweep. This behavior does
not impact FieldFox measurements.
—OFF – Source power is kept ON at all times, including during trigger
Hold mode and between single sweep acquisitions. The RF source
stays at the stop frequency until another sweep begins. This provides
a constant, uninterrupted RF output from the RF OUT port. This
behavior also provides the highest trace stability sweep-to-sweep
which may only be evident while using either single sweep or
Run/Hold. With Battery Saver OFF, the use of a full battery charge is
reduced by approximately 45 minutes.
